摘要

Background

Limitations in mobility of the knee joint result in a massive functional deficit of the knee joint. The treatment should be patient-oriented and not procedure-oriented. In many cases open procedures are necessary.

Aim of the work

Inhibition of movement is often caused by a combination of intra-articular and extra-articular factors. The diagnostics must take these into account and the surgeon must have a good command of the indications and techniques of open arthrolysis. The techniques of posterior capsulotomy, resection of the vastus intermedius muscle, quadricepsplasty according to Judet and lengthening of the patellar tendon are presented.

Results

In 86 cases of open posterior capsulotomy the mean improvement of extension was 17° and postoperatively, no patient had more than 5° of residual extension deficit at follow-up. In 19 patients with severe flexion inhibition a significant improvement for the patient (mean flexion gain 26°) after the procedure could be achieved in 17 cases.

Discussion

Open arthrolysis procedures are complex surgical interventions and should be reserved for experienced knee surgeons. With the correct indications patients can expect a significant improvement in range of motion and quality of life.
